Description

Sheet type flooring with static control properties and manufacturing method thereof

The present invention relates to a flooring material and a method for manufacturing the same, and more specifically, it is formed in the form of a sheet to minimize the connection area to shorten the time required for the connection operation, as well as to expose the polyvinyl chloride chip to the surface to develop color. By this possible, it relates to a sheet-like flooring material having a conductive function and a method for manufacturing the same, so as to eliminate the hassle caused by sanding for color development.

Since most of the building structures are made of concrete, when the concrete surface is directly exposed, there is a problem that the beauty of the inner and outer tubes is deteriorated.

For this reason, interior and exterior materials are added to the interior and exterior walls of the building to enhance the beauty of the interior and exterior.

At this time, one of the interior materials is a flooring material that is installed on the floor surface of the building structure.

Flooring can be divided into tile type, sheet type, floor type, and the like, and it is possible to decorate the floor surface of the building structure due to its unique texture, pattern, and color.

Meanwhile, in the case of a hospital or a laboratory, various electronic devices are used.

At this time, the electronic equipment may be damaged by static electricity.

Therefore, a conductive flooring material as disclosed in Korean Patent Registration No. 10-0225092 (announcement date: January 22, 2013) is installed on the floor surface of a hospital or laboratory so that electrons can be emitted through the conductive flooring material when static electricity is generated. This prevents damage to electronic equipment due to static electricity.

At this time, the conventional conductive flooring was generally formed in a tile shape.

Since the tile-type conductive flooring material is formed of a mixture of polyvinyl chloride chips and carbon sol, the carbon sol surrounding the polyvinyl chloride chips plays a role of conduction, so electrons when static electricity is generated are transferred to the ground wire through the carbon sol and released. Damage to the electronic equipment is prevented.

However, in the case of the tile-type conductive flooring material, the surface of the polyvinyl chloride chip is covered with carbon sol, so that the surface has a black color, so that the decorative effect of the flooring surface is poor.

Therefore, when manufacturing the tile-type conductive flooring, sanding is performed.

When the surface of the tile-type conductive flooring material is sanded, the carbon sol surrounding the surface of the polyvinyl chloride chip is partially removed and the color of the original polyvinyl chloride chip is developed, thereby obtaining the decorative effect of the floor surface by the color of the flooring material.

However, as the sanding operation is added, the operation time is delayed, and there is a problem that the production loss increases.

In addition, in the case of a tile-type conductive flooring material, a plurality of pieces are connected, so in order to transfer electrons in the event of static electricity to the ground wire, an expensive conductive adhesive for electrical connection of each piece is applied to the floor surface or copper wire is applied. Since it had to be laid, there was a problem that the efficiency of the construction work was deteriorated due to the considerable cost and time required for the connection work.

For the above reasons, in the field, attempts have been made to develop a sheet-type flooring material having a conductive function that not only prevents damage to electronic equipment due to static electricity but also facilitates construction, thereby increasing the efficiency of construction work. The situation is not getting results.

The present invention has been proposed in consideration of the above circumstances, and the color of the original polyvinyl chloride chip is removed by removing the carbon sol on the surface through a sanding operation in order to increase the decorative effect of the floor surface by color in the conventional tile-type conductive flooring material. An object of the present invention is to provide a sheet-like flooring material having a conductive function and a method for manufacturing the same, which can solve the problem of delayed working time and increased production loss when the color is made.

In addition, the present invention can solve the problem that the efficiency of the construction work has been reduced as it takes a considerable cost and time to apply an expensive conductive adhesive for the electrical connection of each piece in the conventional tile-type conductive flooring, or to lay the copper wire. An object of the present invention is to provide a sheet-like flooring material having a conductive function and a method for manufacturing the same.

The sheet-like flooring having a conductive function according to the present invention for achieving the above object is formed in a sheet form having a constant thickness, and is formed of a mixture of polyvinyl chloride chips and carbon chips to generate electrons when static electricity is generated through the carbon chips. A main layer to be transferred to the lower portion; It is disposed under the main layer, it is formed of a conductive carbon ink to transfer the electrons transmitted from the main layer to the ground wire to release the transfer layer.

The main layer may be formed to a thickness of 1.5-3.0mm.

The main layer may be provided with a transparent coating layer on the upper surface.

The transparent coating layer may be formed of a conductive UV curing paint.

The transparent coating layer may be formed to a thickness of 1-10㎛.

The transfer layer may be formed to a thickness of 1-10㎛.

In addition, the method of manufacturing a sheet-type flooring material having a conductive function according to the present invention comprises: a raw material mixing step of mixing polyvinyl chloride chips and carbon chips at a constant ratio; A main layer forming step of injecting the mixed polyvinyl chloride chip and the carbon chip into a molding apparatus to form a sheet-shaped main layer having a constant thickness; It includes; a transfer layer forming step of forming a transfer layer by applying a conductive carbon ink to the bottom of the main layer.

The carbon chip in the raw material mixing step is mixed with 1-10 parts by weight compared to 100 parts by weight of the polyvinyl chloride chip.

The particle size of the polyvinyl chloride chip and the carbon chip in the raw material mixing step may be 3-20 mm.

The molding device in the main layer forming step may be a calendar group.

The main layer forming step may include a coating layer forming step of forming a transparent coating layer on the top surface of the main layer.

The transparent coating layer in the step of forming the coating layer may be formed by applying a conductive UV curing coating to a certain thickness on the upper surface of the body.

The sheet-type flooring material having a conductive function according to the present invention and a method of manufacturing the same, since the main layer is formed in a sheet form having a constant thickness, when connecting to the floor surface, the connection portion is minimized compared to the tile-type conductive flooring material, so it is necessary for connection between pieces. Since the time can be shortened, the efficiency of the construction work can be increased.

In addition, the sheet-like flooring material having a conductive function according to the present invention and a method for manufacturing the same are possible because the polyvinyl chloride chip is exposed to the outside, so that the color of the surface is possible. It is possible to shorten the time required for manufacturing efficiency.

In addition, the sheet-like flooring having a conductive function according to the present invention and a method for manufacturing the same include a transfer layer formed by applying a conductive carbon ink, and electrons transferred from the main layer by the transfer layer to the ground line by the transfer layer Since it is transmitted and released smoothly, it is possible to more effectively prevent damage to electronic equipment due to static electricity.

In addition, the main layer 10 may be provided with a transparent coating layer 30 on the upper surface as shown in FIG.

Since the transparent coating layer 30 protects the surface of the main layer 10, damage to the main layer 10 is prevented by the transparent coating layer 30.

At this time, the transparent coating layer 30 is preferably formed to a thickness of 1-10㎛.

When the thickness of the transparent coating layer 30 is less than 1 μm, the protective effect of the surface of the main layer 10 may be reduced, and when the thickness of the transparent coating layer 30 exceeds 10 μm, due to an increase in material requirements As the burden of cost comes, the transparent coating layer 30 is preferably formed to a thickness of 1-10 μm.

In addition, as shown in Figure 4, the sheet-like flooring method having a conductive function according to the present invention includes a raw material mixing step (S1), a main layer forming step (S2), and a delivery layer forming step (S3).

In the raw material mixing step (S1), the polyvinyl chloride chip 11 and the carbon chip 12 are mixed at a constant ratio.

In the raw material mixing step (S1), the carbon chip 12 is preferably mixed with 1-10 parts by weight compared to 100 parts by weight of the polyvinyl chloride chip 11.

When the carbon chip 12 is mixed with less than 1 part by weight compared to 100 parts by weight of the polyvinyl chloride chip 11, electrical conduction performance through the carbon chip 12 may be reduced, and the carbon chip 12 ) When the polyvinyl chloride chip 11 is mixed more than 10 parts by weight compared to 100 parts by weight, the color development of the polyvinyl chloride chip 11 may be reduced due to the carbon chip 12, the carbon The chip 12 is preferably mixed with 1-10 parts by weight compared to 100 parts by weight of the polyvinyl chloride chip (11).

In addition, in the raw material mixing step (S1), the polyvinyl chloride chip 11 and the carbon chip 12 are preferably formed with a particle size of 3-20 mm.

In the main layer forming step (S2), the mixed polyvinyl chloride chip 11 and the carbon chip 12 are introduced into the molding apparatus 200 to form a sheet-shaped main layer 10 of a constant thickness.

At this time, the main layer 10 is the same as previously described, so further description is omitted.

In this main layer forming step (S2), if the molding apparatus is to be able to form the main layer 10 in the form of a sheet, any conventional structure and method may be used, and an example thereof may be a calendar. .

On the other hand, the main layer forming step (S2) may further include a coating layer forming step (S2-1) to form a transparent coating layer 30 on the top surface of the main layer (10).

The transfer layer forming step (S2) A conductive carbon ink is applied to the bottom surface of the main layer 10 to form a transfer layer 20.

At this time, since the transfer layer 20 is the same as previously described, further description is omitted.

On the other hand, the application of the conductive carbon ink may be any conventional method, and as an example, a roll coater may be used.

The detailed description of the manufacturing of the sheet-like flooring material (A) having the conductive function through the method for manufacturing the sheet-like flooring material having the conductive function according to the present invention is as follows.

First, the raw materials are mixed.

That is, the raw material mixing step (S1) in the present invention is performed.

In the raw material mixing step (S1), the polyvinyl chloride chip 11 is mixed with the carbon chip 12 at a constant ratio, and the main layer 10 formed of the raw material in the main layer forming step (S2) Silver transfers electrons when static electricity is generated to the lower portion through the carbon chip 12.

On the other hand, in the raw material mixing step (S1), the polyvinyl chloride chip 11 is only mixed with the carbon chip 12, but the entire outer surface is not wrapped with the carbon chip 12, so that the main layer is formed later. The color of the polyvinyl chloride chip 11 may be developed to the surface of the main layer 10 formed of the raw material in step S2.

Therefore, since the sanding operation for color development of the polyvinyl chloride chip 11 can be omitted, it is possible to shorten the time required for the sanding operation and improve manufacturing efficiency.

Next, the main layer 10 is formed.

That is, the main layer forming step (S2) in the present invention is performed.

In the main layer forming step (S2), the raw material is introduced into the molding apparatus 200, for example, a calendar, and is formed in a sheet form as shown in FIG. 5. Compared to the tile-type conductive flooring (A), since the connection portion is minimized, it is possible to shorten the time required for the connection between pieces, especially the electrical connection between pieces, thereby improving the efficiency of construction work.

At this time, the main layer forming step (S2) may include the coating layer forming step (S2-1), as shown in Figure 7, as the transparent coating layer 30 is formed on the top surface of the main layer 10 The surface of the main layer 10 may be protected by the transparent coating layer 30.

However, as the transparent coating layer 30 is formed on the upper surface of the main layer 10, when static electricity is generated, interference with electron transfer to the main layer 10 may occur.

However, in the present invention, the transparent coating layer 30 is formed by applying a conductive UV-curable coating on the top surface of the main layer 10. As a result of material characteristics, electrons generated during static electricity pass through the transparent coating layer 30 to form the main layer 10 ), So that the electromagnetic transmission interference by the transparent coating layer 30 is prevented.

Next, as shown in FIG. 6, the transfer layer 20 is formed on the bottom surface of the main layer 10.

That is, the transfer layer forming step (S3) in the present invention is performed.

At this time, the transfer layer 20 is formed of a conductive carbon ink, the bottom surface of which is in contact with the bottom surface 100, the electrons transferred from the main layer 10 as shown in Figure 3 is the transfer layer Since it is smoothly transmitted to the ground wire through 20, damage to electronic equipment due to static electricity is prevented.

However, manufacturing time may decrease as time is spent in the process of forming the transfer layer 20 on the bottom surface of the main layer.

However, in the present invention, the transfer layer 20 is formed by applying a carbon ink to a constant thickness. As the transfer layer 20 is simply formed by applying carbon ink without a separate adhesion process, the transfer layer 20 is formed. The decrease in manufacturing efficiency due to the formation of (20) is prevented.

As described above, the sheet-like flooring material (A) having a conductive function according to the present invention and a method for manufacturing the same, as the main layer 10 is formed in the form of a sheet having a constant thickness, the conventional tile when applied to the floor surface 100 Since the connection area is minimized compared to the type conductive flooring material, the time required for electrical connection between pieces can be shortened, thereby increasing the efficiency of construction work, and the color development of the surface as the polyvinyl chloride chip 11 is exposed to the outside. As possible, since the sanding operation for surface coloring during manufacturing can be omitted, the time required for the sanding operation can be shortened to increase manufacturing efficiency, and includes the transfer layer 20 formed by applying carbon ink. Since the electrons transferred from the main layer 10 by the transfer layer 20 are smoothly transferred to the ground line by the transfer layer 20, they are discharged. It can be more smoothly prevented from damaging the electronic equipment.

The present invention as described above is not limited to the above-described embodiments, and thus can be changed within a range not departing from the gist of the present invention claimed in the claims, and such changes are defined by the following claims It is within the scope of the invention.
